Many different brands of bottled water will vary in their alkalinity, while some remain constant. Most drinking waters hover right around the classic PH of 7, while some are a bit higher. The brands of bottled water that are the most alkaline include Fiji (7.5), San Pelligrino (7.7), and Trinity Springs (9). Other brands can also be above or below the alkalinity of normal water depending on the batch. Brands such as Arrowhead and Poland Springs can range from a PH of about 6 to 7.6.
The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. Sodium hydroxide, NaOH, also known as caustic soda or lye, is of great industrial importance. Calcium, barium, and strontiumâall alkaline earth metalsâform soluble hydroxides that are strong bases but are less stable than the alkali hydroxides. Of these, calcium hydroxide, Ca(OH)2, commonly known as slaked lime, is the most common. With the exception of thallium hydroxide (TlOH), the hydroxides of other metals, such as magnesium, iron, bismuth, nickel, cobalt, and copper, are only sparingly soluble in water but neutralize acids.
